I don't want to use any of these userspace tools in the long run, but in order to see if cpufreq does work it seems to me a good idea to check this
by using either cpufrequtils or cpufreqd. But the thing is it does not work at all. Maybe i have to rebuild my whole system and see if it works then.
Is my kernel .config correct ? I dont even know what to try now, i am lost !

I guess that's what blocks it for me in some way. Mainboard is MSI P35 Neo2 FR (BIOS 1.5) with an E8400 CPU. According to my BIOS, "Intel EIST" is enabled but I still get the same error as above ("could not insert 'acpi_cpufreq': No such device"). Same for speedstep-centrino and pcc-cpufreq.

As it is enabled in BIOS without any effect I guess there's either some hardware that blocks usage or there's some BIOS bug. I didn't have the nerves to update it yet, though._________________nohup nice -n -20 cp /dev/urandom /dev/null &

Same here:

Code:

$ modprobe acpi-cpufreq
modprobe: ERROR: could not insert 'acpi_cpufreq': No such device

$ modprobe speedstep-centrino
modprobe: ERROR: could not insert 'speedstep_centrino': No such device

This is an Acer Z5610 All-in-one PC with this an Intel G45 Chipset and this CPU: Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz

This is the latest BIOS version with supposedly some Linux bugfixes. All I can find in the bios:

Another issue, after halting the system, some harddisk or fan is still running, I need to press and hold the power button for completely turning off the machine. Seems to be another ACPI issue, no?_________________ppc:PowerBook5,8 15"(1440)-G4/1.67,2G | amd64:Acer Z5610 (Core2QuadQ8200),i5-3470,VMware VM @ i7-2620M | amd64-prefix:OpenSuse | Lila-Theme
